.
SATELLITE ANALYSIS AND TRENDS...DERIVED GOES SATL WINDS INDICATE BROAD
JET STREAK EXTENDING FROM THE GREAT LAKES REGION TO THE NE OVER NRN NEW
ENGLAND. LATEST WV/IR IMAGERY SHOW ENHANCEMENT FROM S/WV FEATURE MOVING
TO THE NE THRU NERN TN/ERN KY. THIS SHOULD INCREASE FORCING FOR ASCENT
ACROSS MUCH OF MID-ATLANTIC OVER THE NEXT FEW HRS. LATEST SFC OBS INDICATE
CURRENT FREEZING LINE ACROSS CNTL VA JUST N OF OFP/LYH/MKJ...EXTENDING
TO THE SW INTO FAR ERN TN. MOST OF THE AREA OF DISCUSSION HAS ALREADY
DROPPED SUBFREEZING AND COLD AIR CONTINUES TO DRAIN SOUTH THRU THE REGION
BEHIND THE COLD FRONT.
.
LATEST SNOWFALL RATE PRODUCT (SFR) PASS FROM METOP-A POLAR SATELLITE AT
1529Z INDICATES 0.04"-0.06"/HR LIQUID-SNOW EQUIVALENT IN-CLOUD RATES
ACROSS SRN WV/ERN KY. MELTING LAYER ALOFT IS CURRENTLY INFERRED IN
THE PASS IN FAR ERN KY...SO SNOWFALL RATES WITHIN THIS BAND MAY REACH
1.0"-2.0"/HR WHICH ALIGNS WITH CURRENT SPC MESO DISCUSSION. ANOMALOUSLY
HIGH MOISTURE IN PLACE OVER MID-ATLANTIC WITH A TROPICAL PAC CONNECTION
EVIDENCED BY CIRA EXPERIMENTAL MULTI-LAYERED PW IMAGERY SUPPORTS THE
HIGHER SNOWFALL RATES WITHIN THE BAND. ANTICIPATE THE MOD/HVY SNOWFALL
TO OCCUR INTO THE AFTERNOON/EARLY EVENING ACROSS THE MID-ATLANTIC AS THE
S/WV TRANSLATES INTO AN AREA OF 85H-70H FGEN FORCING DRAPED ACROSS CNTL
VA/SRN MD. SEE ANNOTATED SATELLITE GRAPHIC SHOWING THE EXPECTED AREA OF
HEAVIEST SNOWFALL OVER THE NEXT SEVERAL HOURS ASSOCIATED WITH HIGHEST
SNOWFALL RATES SEEN IN LATEST SNOWFALL RATE PRODUCT IMAGE.
.
AN ANNOTATED SATELLITE GRAPHIC SHOWING THE HEAVY PRECIPITATION THREAT
AREA SHOULD BE AVAILABLE ON THE INTERNET ADDRESS LISTED BELOW IN
APPROXIMATELY 10-15 MINUTES.
